In the Jan. 21 episode of the ABC drama, when adult-video magnate Beau Randolph (Entourage‘s Jordan Belfi) is murdered, Castle and Beckett are confronted with a lengthy list of suspects with motive. Arrow bad girl Kelly Hu guest-stars as Scarlet Jones, a bodyguard who failed to stop Beau’s murder but who does manage to attract the attention of a certain NYPD detective.

This is gonna be good! I love Kelly Hu, she seems like a great match for Espo. It’s hard, impossible, in fact, to get invested in Esposito and Lanie when we’ve literally been given nothing to invest in. We saw one hookup and then nothing since. The “hints” of them would be laughable if it weren’t so frustrating. If not with each other, lets SEE them pair up with others! I’m loving these stills – looks hot.
